To all whom it may concern: I

Be it known that I, CHARLES F. ROBIN- soN, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented a certain new and useful Improvement in Motor- Car Axles, of which the following is a specification;

My invention relates to an improvement on those car wheel axles on which the liner of the motor casing of a motor propelled car bears, and it is applied after the journal parts of the axle on which the liner bears, have-worn out or have become too small. The object of my improvement is to pro; long indefinitely" the life of the axles, thereby saving much labor and material. I at stain this object by metal plates inlaid, welded or brazed in, and made-solid with, the axle where it has been worn by the liner of the casing of the motor, thus restoring the axle throughout its entire length to its original formand efliciency. In such metal plates consists, essentially, my improvement.

It is illustrated in the accompanying drawings, embodying my improvement, in which- Figure I is a side view of the axle of a motor car on which the liner of the casing bears, broken into two parts, the wheels and the casing of the motor being omitted, one

of said two parts showing one of said worn journal parts Without the said metal plates, and the other of said two parts, the other of said Worn journal parts with the metal plates inlaid therein, partly broken away and sectioned transversely through the center. Fig. II is a transverse section through the worn journal parts. The metal plate -C is metal formed to fit the worn journal parts of the axle and is of such size and shape as. to restore the axle to its original form and efficiency, It may consist of one piece or of two or more pieces preferably four, as shown in the drawing) or: its convenient insertion. The pieces forming the plate may be secured to each other, and to the worn'journal parts of the. axle in any one. of the well known ways of. securing metal to metal.

I claim:

The herein described method of repairing worn axles which consists in cutting down an intermediate worn portion of the axle to form a reduced portion of a definite length, fitting about the cut down portion of the axle one ormore filling segments, each of a le th eqilial-to the length of qthe reduced -por 'on, t

e segmentswhen. fitted about the reduced portion completely ensheathing the same, permanently uniting the said segments to the surface of the reduced portion and to each other, and finally truing down the segments flush with the unworn surface ofthe axle. CHAS; F. ROBINSON.
